Camera to picatinny mount?

The best way is the most expensive. Don't Cedric Bwalton and a few others mount their camera on their scope. Here's the Eagle Eye system, it works like a periscope but it's very expensive

Yes it's crazy-I am hoping it drop like GPS units. I check on this system every so often but they are still priced up there.

Yeah that one is expensive but if ur serious about starting a channel it might pay off. The ATN Shot Trak HD is also something you might like.

Michael I used a short add a rail for an AR-15 handguard that already had a hole in it. I use a 1/4 20 screw to mount it to the bottom of my camera with the picatinny rail facing down. Then I put a scope ring that mounts to a picatinny rail upside down on my scope and just clamp the upside down rail into the ring on the scope. Then I just put rings on all the rifles I plan on filming with so its easy to switch it between different rifles and it doesnt need to be adjusted when you switch it from rifle to rifle. This of course doesnt give you the video thru the scope but from on top so you would need a different set up to get the scope cam view.

That's super expensive. Choice between buying this or a new gun, my money goes to the gun!!
